Title: Titanium alloy annular forging prodn - by repeated deformation
IPC: C22F1/18
Filed: 1970-12-02
Abstract: Ingot of Ti alloy with 2-phase alpha + beta structure contg. >=30% beta-phase is shaped to annular forgings for use under high stress, esp. sliding shroud band rings of turbine generators working with >=500 MW, by repeated deformation in axial, radial and tangential direction, e.g. drawing, upsetting, punching and rolling. Total degree of formation in each of these directions is >=60% of total deformation. Direction of deformation is changed each time and degree of deformation is >=40% on last forging. Heating temp. is gradually lowered from first forging temp. which is 50-80 degrees C above phase transition temp. (T) of alloy from beta to alpha + beta structure, to a temp. which is 20-30 degrees C below (T) in last forging step. After completing plastic deformation, the blank is annealed at a temp. below (T).

IPC: B29D1/00
Filed: 1972-09-14
Abstract: 1377109 Trim strips STANDARD PRODUCTS CO 26 Sept 1972 [29 Dec 1971] 44454/72 Heading B6G An end finish for a trim strip of plastics material is produced by removing a portion of the trim strip material such that the remaining portions of the strip material define a recess having at least two edges, and extending through the entire thickness of the trim strip, displacing the remaining portions relative to one another to bring the two edges of the recess into juxtaposed relationship, and interconnecting the remaining portions to retain the two edges in juxtaposed relationship. The interconnection of the remaining portions of the trim strips may be achieved by bonding or by the use of fasteners and preferably by heatsealing the juxtaposed edges together. Preferably the strip material is heated prior to displacement of the trim strip portions to facilitate such displacement or to facilitate both the displacement and heat-sealing of the juxtaposed edges. Heating can be achieved by a heating block having a contour corresponding to that of the recess. Displacement of the trim strip portions to bring the recess edges into juxtaposition can be achieved by using an appropriately contoured forming block. The trim strip may be made of polyvinyl chloride. As shown in Fig. 2 and 3 a portion of a trim strip material is removed whereby remaining side portion 30 and remaining intermediate portion 32 define a recess 34 and remaining side portion 36 and remaining intermediate portion 32 define another recess 38. Recess 34 has two edges 30a and 32a and recess 38 has two edges 36a and 32b. Portions 30 and 36 are cut to a longitudinal length which provides for each to be displaced laterally inwardly relative to the intermediate portion 32 and to terminate in an abutting engagement. Terminal ends 30b and 36b of side portions 30 and 36 are tapered to provide for the terminal ends to be disposed in abutting relationship. The interconnection of the side portions 30 and 36 with intermediate portion 32 is achieved by heatsealing. Heating can be achieved by conductive, radiant, hot gas, or induction heating. Preferably conductive heating is employed by using a heating block 40 provided with electric heating electrodes in recesses 42 thereof. Lateral displacement of the side portions 30 and 32 is preferably achieved after the trimstrip has been heated by a pair of laterally reciprocable die elements 46, 48. Other end contours of the trimsttip are described and illustrated.

Patent FR-2272471-A1 (FR)
Title: Core assembly for three limb transformer - without joints in flux path at core centre
IPC: H01F41/02
Filed: 1974-05-21
Abstract: In the manufacture of star shaped three limb transformer cores it is required to eliminate undesirable air gaps at the core centre where the three limbs meet. This difficulty is overcome by making the limbs from a single piece of material. For example a ring of transformer core steel of appropriate diameter is placed in the centre of three rams (2). These rams are then driven inwards toward a common centre, and deform the ring into a three limbed star (1). A continuous iron path thus results. In an alternative form a V-shaped core element may be used thus giving continuity between adjacent limbs.

Title: Preparing natural tissues, valves, blood vessels, for transplant - curing fluid at physiological pressure restores tissues natural shape
IPC: A61F2/24
Filed: 1975-06-26
Abstract: Natural tissues are prepd. for transplanting by subjecting the parts of the organs or vessels which, when transplanted and exposed to pressures within the biological range, take up their pristine form, to the action of a curing fluid at a similar pressure within the biological range, so that they readopt their original form; whilst the remaining parts of the tissues are subjected to fixing by a curing fluid at a lower pressure. In its natural condition, the vessel may have a shape identical with or different from the shape given to it. This may be a "U"-form, and during exposure to the fixing fluid, guides such as glass tubes, smaller in diameter may be inserted into the vessel, or the guide may consist of a tube curved to the required shape and having an inside diameter near enough to the outside diameter of the tissue under pressure. Overcomes the problem of shrinkage during curing and subsequent expansion when implanted, the degree of which cannot be anticipated with complete accuracy. Heart valves liable to leakage can be rejected beforehand, and setting without undesirable tension is simplified.

Title: Piston valve pneumatic hammer - has differential piston with edges chamfered for gradual opening of ports
IPC: B25D9/16
Filed: 1975-08-05
Abstract: The pneumatic hammer consists of a cylinder housing which contains a piston whose rod engages with the work. A plate valve is mounted in one end of the cylinder. When the cylinder is at the end of its stroke, it clears an outlet hole so that the pressure in the cylinder drops and the plate valve is closed by the inlet air. When the plate valve is closed, the inlet air is directed to a bypass channel to underneath the piston which will be pushed up. The air above the piston is compressed, the plate valve opens again and the compressed air supply is again admitted above the piston which is forced down.
